采用漂白粉代替重铬酸盐作氧化剂改进了由环已醇合成环己酮的方法,改进后的方法有如下特点:(a)得率较高;(b)成本低;(c)无环境污染;(d)操作既简便又安全。采用正交设计方法找出了最佳的实验条件。合成环己酮的沸程、折射率、红外光谱等都与文献记载相符合。 Using bleaching powder instead of dichromate as oxidant improves the method for synthesizing cyclohexanone from cyclohexanol. The improved method has the following features: (a) high yield; (b) low cost; (c) no environmental pollution ; (d) The operation is easy and safe. Using orthogonal design method to find the best experimental conditions. Synthesis of cyclohexanone boiling range, refractive index, infrared spectroscopy and so on are consistent with the literature.
